Beit knowriathat I, CHARLES S. WILMETH,

a citizen of the United States, residing inthe city of St. Louis,- in the State of Missouri, have ments in a Combined Agricultural Machine, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings," forming part of this 1o specification.

My invention relates to a combined machine for agricultural purposes-designed for multi-- lple services in the tilling ofsoil, the construction of the machine and the parts attachable x thereto being such as to render it of utility in breaking ground, pulverizing, harrowing, tamping, and marking the upturned soil and covering small grain and also for depressing weeds, grass, or other growth to be turned unzo der th surface of the ground.

Figure I is a top or plan View of my combined machine. Fig. II is a side eleva-tion of the machine. Fig. III is a view partly in vertical section taken on line III III, Fig. I, and

'2 5 partly in elevation. Fig. IVis arear elevation of the machine. Fig. V is a vertical transverse sectional view of the machine, taken on the irregular line V V, Fig. I. Fig. VI is an enlarged detail View, partly in-elevation and 3o partly in section, of the driving-gear mechany Fig. VII

ism, the parts being shown in gear. is a view similar to Fig. VI with the parts shown out of gear. Fig. VIII is an enlarged cross-sectional View taken on line VIII VIII, Fig. IX is a detail top view of the weed-depressing sweep. Figs. X to XVI, inclusiye, are detailviews of the detachable bits used upou the machine. Fig. XVII is a vertical section of one of the bits and mold boards.

The construction of machine forming the subject-matter of this invention provides for the operation of soil-workin g bits or members in a circular or rotative manner, whereby the soil is eIecI-ually cut up and worked, either by 45 breaking it, cultivating, or otherwise treating it subsequent to thc original breaking operation. By the construction that provides lfor a circular action of the soil-working members I have produced an agricultural apparatus of 5o great merit that acts upon and in the soil in a most effectual manner to thoroughly break 5 invented certain new" and useful Improveitup, put it in condition for the seed to be planted, and capable ofother operations in treatment thereof without dragging or rolling upon the ground and with the least degree of lfrictional contact to render it leasy of opera- 1 designates the platform of the machine, (see Fig. V,) having attached thereto an axleframe 2, that receives the axles 3, 'mounted in the ground-wheels 4.

5 designates steering-wheels journaled to an upright 6, that is surmounted by a fifthwheel 7, forming anconnection between vsaid upright and the platform of the machine.

8 is a draft-'tongue attached'to the upright 6. 9 is a seat mounted on the platform 1. 10 designates drop-bars carried by the platform 1, that receive the pivotal connection at 11 (see Fig. III) of carriers 12, by which the soil working parts of the machine are supported. The carriers l2 are provided with apertured arms 13, either one of the apertures in which is adapted to receive a bolt or pin 14, by which lift-levers 15 are connected to the carriers. 'lhe lift-levers 15 are swingingly mounted in brackets 16, that are provided with a series of apertures, into either of which the pivotpins of the levers may be inserted. By providing the series of apertures in the carrier arms 13 and brackets 16 the lift-levers may be arranged in varying position in said parts in order to effect greater or less throw of the carrier 12 in the movement of the lift-levers. 'lhe forward ends of the lift- -levers are provided with .spring-latches 17,

having toothed heels 18, that are adapted for Vengagement with vertical rackslf), carried by the platform 1 of the machine.

20 designates hanger-arms extending downwardly from the carriers 12 and adapted to receive the connection of crankhangers 21, that are loosely hung in the hanger-arms..

22 designates pitmen that are provided with' rearwardly-extending arms 23, in which the arms of thehangers 2l are mounted, the hangers being of U sh'apeIseen in Fig. I) toprovide for their application to the pitmen.

2l designates internal gears carried by the ground-wheels 4 of the machine.

25 designates horizontal boxes supported at their forward ends from the platform 1 by drop-hangers 26 and having their rear ends mounted upon the axles' 3. y 27 designates shafts positioned in the horizontal boxes 25`and on which are mounted internal gears 2S and pinions 29, the lastY named of which are adapted for engagement with the teeth of the internal gear 24. .The shafts 27 are journaled in slides 30, (see Figs. V, VI, and VII,) adapted'toreciprocate in the boxes 25, upon the movement of which the internal gears 28 and pinions 29 may be shifted for the purpose of throwing the parts of the vmachine out of gear, as will hereinafter-appear.

31 'designates crank-shafts mounted in bearings on the boxes and having fixed thereto pinion's'32, adapted to mesh with the teeth-of the internal gear 28. for the purpose 'of driving said crank-shafts on the operation yare forked, as seen in Figs. VI and VII, to

straddle studs 36 on the slides 30.

37 designates posts mounted upon the boxes .25 and provided withapertured upper ends.

38 designates rock-shafts mounted in the shifters 33 at their upper ends, and 39 designates socket-arms carried by said rock-shafts and lprovided with notches 40. The socketarms are provided with handles 41, by which they may be lifted and lowered.

42 designates stems provided with threaded ends 43, that are seated in the threaded apertures of the post 37.

44 designates two series of fingers projecting from the sides of the stems 42, that iit into the notches 40 of the rock-shaft-carried arms 39 to hold said arms frommovement on said stem when applied thereto. When the machine is ingear, the rock-shaft-carried arms 39 are moved into the position seen in Fig.

VI, so that the notches 40 receive both series of fingers 44 on the stems 42, thereby holding the Shifters in upright position, so holding the slides 30 that the pinions 29 are main-4 tained in engagement with' the' teeth of the internal gear 24, and the internal gear 28 is maintained in engagement with the pinions 32 of the crank-sh afts 31. Torthrow the parts y out of gear, the rock-shaft-carried arms 39 are lifted by the handles 41 out of engagement with the lingers 44. The stems 42 and the arms are moved into the position seen in Fig. VII,

so that the notches in the rear ends of said arms may be 'fitted to the fingers 44 at the forward ends of the stems 42, thereby moving gime?" the ends of the Shifters 33 forwardly and'causing'their lower ends to be thrownV vthe internal gears 28 out of engagementwith the pinions 32. When the parts have been so manipulated, the ground-wheels may travel upon the ground in the transportation of the vmachine without imparting movement to the gearing and the pitmen connected thereto.

For the' purpose of causing the pitmen 22 to'be operated correctly and the crank-hangers 21 and cran-ks 31 to operate uniformly and in unison with each other I utilize equalizers that are applied to the pitmen both -in front andrear of the crank-hangers 21 and are fulcrumed to the carriers 12, by which the' pitmen are supported. l

45 vdesignates the forward bars of these equalizers, that are pivoted at 46, forward of the crank-hangers 21, to the pitmen and each of which is provided with a longitudinal slot 47, that receives a fulcrum-pin 48, seated in the carrier, by which the individual pitman ,corresponding thereto is supported.

49- designates the rear equalizer-bars, that are pivotally connected at 50 to the arms 23 `of the pitmen and which are pivotally connected at .their upper ends to the forward bars 45, the connection being preferably made through the medium of links l51, the equalizer, composed of the bars 45 and 49, being connected to the pitmen, as stated, and one vof the bars having fulcrum connection with the pitman-carrier 12. 'The rear portion of each pitman issupported by each equalizer in such manner'that the crank-hangers 21 arealways maintained in a uniform position in relation to the drive-cranks 31 at lthe forl ward ends of the pitmen. thus rendering it impossible for the rear end of the pitmen to fall out of'alinement with the forward ends. I will next describe the bits or soil-working members that are used in connection with my machine.l

Referring first to what I term spader-bits and which are shown in Figs. l, II, III, IV, and X of the drawings, 52 designates the bits connected to the pitman-arms 23 by pivotclips 23,?, pivoted a't 23b to thepitman-arms 23. (See Figs. II and III.) At the lowerend of each bit 52 are rearwardly-turned flanges 55, and mounted on each bit are series of clips 56. 57 designates adjustable moldboards applied to the bits 52, seated within the flanges (see Fig. X) and provided wit 1 a series of supporting-rods 58, that are pivotv ally connected toclips 59 near -the lower edges of the moldboards and are adjustably seated in the clips 56 on the bits, in which they are held by pins or bolts 60,-as most clearly seen in Fig. XVII. 61 designates adjustment-rods pivoted to clips 62 near the upper edges of the moldboards 57 and movably held in clips 63 on thebits 52, these last- IKK 'named rods being adapted to be so held in said clips 63 as to effect upward or rearward 'inclination of the moldboards 57 with relation to the bits, so that they will extendrearwardly |therefrom in inclined directions as y desirablefor their soil-turning action in the ground. tionof the bits 52, they are pivotally -connected to the pitman-arms, as stated, and the apertures 53 therein receive arms 5l, carried by the pitmen and adapted to receive keys 54, by which the bits are held in varied inclinations. The spader-bits just described are designed for use in cutting and turning the soil as the'iirst step in preparing it for a crop and also for covering the crop of small grain previously planted, which may be covered a't the same 'time that the soil iscut or broken.

In Fig. XI, I have shown a bit suitable for marking ground, which comprises a frame 52, that is `designed to be attached to the pitmen in the same manner as the bits 52 and has a shoe 57 provided with a markervtongue 57", adapted to produce a groove within the soil in the travel of the machine.

In Fig. XII, I have shown a marker-bit composed of a plate 52", having a shoe 57C, provided with a series of tamping-tongues 57d, that are adapted to operate upon the ground to press the soil onto seed sown and which may also be of service in marking the soil for the reception of small seeds.

In Fig. XIII, I have shown a digger-bit composed of a frame 52e, to which is aixed a series of broad cutters 570, intermediate of which a :e a series of narrow cutters '57f, the cutters beingheld between straps fixed to the frame 52.

'4m In Fig. XIV, I have shown a barrow-bit composed of a frame 52, having a shoe 57, that is provided with a series of teeth 571.

In Fig. XV, I have shown a cultivator-bit that is composed of a plate 520, that has affixed to it a blade 57i.

In Fig. XVI, I have shown a bit composed of a plate 52f, having afiixed thereto a blade 57 3 and also carrying at the edges of said b lade narrow teeth 57 that are adapted to operate in the soil in conjunction with the blades between them.

(iidesignates a sweep that is swingingly I mounted at G5 upon the forward end of the platform l of the machine and extending rearwardly therefrom to a position in the rear of the ground-wheels 4, but forward of the cutter-bits of the machine. This sweep is adapted to' move in proximityto the ground, where it serves to depress weeds, stalks, or other growth, in order that they may be readily turned under the soil as it is workedby the bits that subsequently to the passage of the sweep operate therein. The sweep 64 is supported and held by a bit 66, that is mounted on a frame 67, which surmounts the platform l and extends downwardly to the rearend of the sweep, which is provided with a series of In order to obtain desirable inclinaapertures (38, adapted to receive pins 69,- (see,` Fig. II,) by which thc sweep is supported and held.

. In the practical use of this .machine the pitmen 22 are constantly reciprocated by the driving connection to the crank-axles 3l, that are fitted to the forward ends of the pitmen, and the reareuds of the pitmen rising and falling upon the turning of the crank-hangers 21, by which their rear ends are carried. During the reciprocating and rise-and-fall motion of the pitmen' the bits carried by said pitmenare constantly movedlin a circular direction, as indicated by full and dotted lines, Fig. III, their motion being upwardly, forwardly, and then downwardly into the ground and rearwardly out of the ground, in which action they constantly throw the soil rearwardly in the case of the use of the bits provided with moldboards, while in the use of the'bits provided with the other soil-working parts they act uponthe soil in a-manner that 'causes thorough pulverizing, tamping, marking, andv seed-covering action, all of which will be apparent whenthe motion imparted to the bits is considered.
